Apache start / restart

Test web pages

Point your web browser to
http://<your lpar2rrd host>/lpar2rrd/ as soon as you configure LPAR2RRD
Do not forget to ensure that Apache starts after the OS reboot (there must be a starting script in /etc/rc.... )

Configuration

Continue by define VMware hosts (vCenter/ESXi) in the UI:http://your_web_server/lpar2rrd/
Add credentials for every vCenter or ESXi if it is not managed by the vCenter
Settings ➡ VMware ➡ New ➡ place credentials (username in format: lpar2rrd@your_domain)
Test vCenter connection via "Test" button.

Run "Connection test" for each added vCenter to assure that it is ok

When you use Virtual Appliance then use "run data load" button and wait a bit.
Your vcenter appears in a few minutes after Ctrl-F5 (browser refresh). That is all!

When you do not use Virtual Appliance then run ./load.sh which starts collecting of VMware data

$ cd /home/lpar2rrd/lpar2rrd
$ ./load.sh

You should see VMware hosts in the UI when load.sh finishes (reload the UI in the browser via Ctrl-F5)

Troubleshooting

You are on AIX and you get this error when manually checking vCenter connection:

The reason is that user you have configured for retrieving data from the vCenter probably has not read access to whole vCenter and it cannot access all required perf counters.
Consult user rights setup with your vCenter administrator.

OS agent is add-on feature for monitoring from operating system level.
It is monitoring CPU, memory utilization, paging, LAN and SAN traffic on all adapters.
It requires the OS agent deployment to every monitored VM.
The agent is written in Perl and calls basic OS commands to obtain required statistics like vmstat, iostat.

Notes

LPAR2RRD agent is available since 3.56 release.
You will not need to upgrade LPAR2RRD agents regularly with each LPAR2RRD upgrade.
Read release notes if that is necessary.
Check OS agent upgrade steps.
